    Hi Qt community
    I have an gui application which source code is written in Visual studio C++ i want my application to run in both the linux and windows and for some other updates i am shifting towards Qt.
    i have to write the whole application in Qt from the beginning now i wanted to clear some doubts before starting

    1. what are the points i need to consider before starting to write the application in Qt
    2. since both are C++ will i be able to use some code snippet from the existing source code
    3. between using widget and view (eg: treewidget and treeview ) which is better

    this is my first time interacting in this Forum Please be kind i really appreciate your valuable suggestion thanks in advance

      1. This is quite generic question. Do you have any specific concerns? One thing to consider is Qt license - if you go with the open source version you have to fulfil LGPLv3 license.
      2. Sure
      3. Depends. Widgets should be used for small amount of data with simple logic. Else go for views.
